Member Function Documentation

setInnerPolicy()

void ndn::security::v2::ValidationPolicy::setInnerPolicy

(

unique_ptr< ValidationPolicy >

innerPolicy

)

Set inner policy.

Multiple assignments of the inner policy will create a "chain" of linked policies. The inner policy from the latest invocation of setInnerPolicy will be at the bottom of the policy list.

For example, sequence of this->setInnerPolicy(policy1) and this->setInnerPolicy(policy2), will result in this->m_innerPolicy == policy1, this->m_innerPolicy->m_innerPolicy == policy2', and this->m_innerPolicy->m_innerPolicy->m_innerPolicy == nullptr.

Exceptions

std::invalid_argument

exception, if innerPolicy is nullptr.

hasInnerPolicy()

bool ndn::security::v2::ValidationPolicy::hasInnerPolicy ( ) const

inline

Check if inner policy is set.

getInnerPolicy()

ValidationPolicy & ndn::security::v2::ValidationPolicy::getInnerPolicy

Return the inner policy.

If the inner policy was not set, behavior is undefined.

setValidator()

Set validator to which the policy is associated.

checkPolicy() [1/3]

virtual void ndn::security::v2::ValidationPolicy::checkPolicy ( const Data &  data, const shared_ptr< ValidationState > &  state, const ValidationContinuation &  continueValidation  )

pure virtual

Check data against the policy.

Depending on implementation of the policy, this check can be done synchronously or asynchronously.

Semantics of checkPolicy has changed from v1::Validator

• If packet violates policy, the policy should call state->fail with appropriate error code and error description.
• If packet conforms to the policy and no further key retrievals are necessary, the policy should call continueValidation(state, nullptr)
• If packet conforms to the policy and a key needs to be fetched, the policy should call continueValidation(state, <appropriate-key-request-instance>)

Implemented in ndn::security::v2::ValidationPolicyCommandInterest, nfd::CommandAuthenticatorValidationPolicy, ndn::security::v2::validator_config::ValidationPolicyConfig, ndn::security::v2::ValidationPolicyAcceptAll, and ndn::security::v2::ValidationPolicySimpleHierarchy.

checkPolicy() [2/3]

virtual void ndn::security::v2::ValidationPolicy::checkPolicy ( const Interest &  interest, const shared_ptr< ValidationState > &  state, const ValidationContinuation &  continueValidation  )

pure virtual

Check interest against the policy.

checkPolicy() [3/3]

virtual void ndn::security::v2::ValidationPolicy::checkPolicy ( const Certificate &  certificate, const shared_ptr< ValidationState > &  state, const ValidationContinuation &  continueValidation  )

inlinevirtual

Check certificate against the policy.

Unless overridden by the policy, this check defaults to checkPolicy(const Data&, ...).

Depending on implementation of the policy, this check can be done synchronously or asynchronously.
